When personnel platforms are lifted with a telescopic crane, what kind of system is provided for damage prevention?

When personnel platforms are lifted with a telescopic crane, a two-block damage prevention system is essential for ensuring safety during operation. The two-block system is designed to prevent dangerous situations by detecting when the hook or block comes too close to the boom tip. If this proximity occurs, it can lead to equipment damage or even catastrophic failure, risking the safety of personnel on the platform. The system typically includes an electronic or mechanical signal that alerts the operator to stop the lift or adjust the load, effectively preventing the blocks from colliding.

This system is especially critical when carrying personnel because the stakes are significantly higher; any failure or accident can result in serious injuries or fatalities. The implement of such safety measures demonstrates a commitment to adhering to strict operational safety standards in crane operations, particularly in scenarios where human lives are at risk.

Other options, while potentially beneficial in their own right, do not directly address the issue of preventing damage from two-blocking during personnel lifts. For instance, a load weight monitoring system helps ensure that the crane is not overloaded, while a positioning accuracy system aids in precisely placing loads. A safety cage might enhance the protection of personnel in other contexts, but it does not prevent equipment damage related to two-blocking.
